摘要
目的建立一种适用于食品包装材料中羟基苯醚的气相色谱/质谱检测方法。方法采用索氏提取法,以二丙醚萃取提取样品中二苯醚类物质,经色谱分离后采用质谱检测,保留时间、分子碎片峰定性,外标法定量。结果二苯醚类物质回收率为88%~109%,相对标准偏差<3.9%,检测限0.032~0.067mg/L。结论本方法便捷、重现性好,适用于各类食品包装材料中二苯醚类物质检测。
Objective To establish a method for determination of diphenyl ether in food packing materials using gas chromatography/mass spectrometry. Methods The diphenyl ether in food packing materials was ex-tracted by soxhlet extraction with dipropyl ether, and then qualitatively anlyzed using mass spectrometry detector. The diphenyl ether were qualitatively determined by retention time and molecular fragment peaks. The external standard method was applied for the quantification. Results The recoveries of typical diphenyl ether were be-tween 88%~109%with RSD less than 3.9%and limit of detection was 0.032~0.067 mg/L. Conclusion The me-thod is convenient and reproducible for determination of diphenyl ether from the food packing materials.
